timer and thermostat
Just checked the condition of our circulator action yesterday. The time is set to 12 hrs on and 12 hrs off with a 32-40 degree thermostat in-line. It looks like it was keeping the 12' wide x 25' long area between the fingers of the U-dock clear, with some clearing outside the fingers, but the frigid temps last week caused a partial freezover of thin ice. When the temps get back to "normal" it should re-clear. So, I left the timer as-is for now.
